IMPROVEMENT IN STEAM-CYLINDER LUBRICATORS.

Specification formin g part of Letters Patent No. 179,585, dated July 4,1876; application filed June 2, 1876.

To all whom it may concern:

Be it known that I, ELIJAH McOoY, of Ionia, in the county of Ionia andState ot'Michigan, have invented certain new and useful Improvements inSteam-Cylinder Lubricator; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

The nature or my invention consists in certain improvements in the double-seated valve of the steam-cylinder lubricator for which LettersPatent No. 173,032 were granted to me February 1, 1876, as will behereinafter more fully set forth.

- In the annexed drawings, Figure l is a vertical section ofmy improvedsteam-cylinder lubricator. Fig. 2 is a perspective view of the valve. 7

1) represents the oil-cu p A, the central tube,

v with enlargement B. O is the regulating-tube,

reduced in diameter at its lower end. ab are the valve-seats; 7c, theoil-chamber; d, the double valve, and e the valve-stem, all these partsbeingconstructed and arranged substantiallv in the same manner asdescribed in my former patent above referred to. In that case, however,the double valve and its seat were made solid; and I have found, bypractice, that I cannot inject cold oil in acylinder using steampacking,which is very much needed when such packing gets gummed up. To obviatethis difficulty is the object of my invention ,and to this end ahole-passage, m, is

made vertically from the upper end of the on the seat stationary, coldoil may be admit ted to the cylinder while the engine is in motion, withthe top ot'the cap removed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the oil-cup D, central tube A, with enlargement B,perforated regulating screw-tube 0, reduced in diameter at its lowerend, and forming the oil-chamber k, the valve-seats a b, the doublevalve 01, having stem 0 with vertical oil-passage m from the upper enddownward to below the valve, and open at n, all constructedsubstantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own, I affix my signaturein presence of two witnesses.

ELIJAH MCCOY.
